Abstract

A magnetic circuit for generating the mechanical power and the electric power comprises a rotator (10) in a mechanic dynamic power generation device, an electric power generation device and a magnetic flux circulation induction device. The rotator generates a mechanical revolving force by using the electric energy and also convert the mechanical revolving force into the electric energy again, particularly to the rotator in which the mechanic energy can be obtained by using the attractive and repulsive force of the magnetic flux after the electric energy is converted into the magnetic energy when the revolving force is obtained from the electric energy and the magnetic circuit, and the magnetic induction method that the magnetic flux of a revolving field magnet (2) is induced to armatures (3, 4) by the mechanic energy and converted into the electric energy by crossing the coils (3c) wound around slots (3a, 3b) on the armatures (3, 4).
